I just received my BC296D and I have figured out just about everything from this great website, about my scanner and how to use it. I do have one question that I can't seem to find the answer on myself. I have no clue what CTCSS and DCS is, and what to set it on. I only monitor Motorola Type II analog and digital as well as a few conventional channels. Do these systems require the use of the CTCSS and DCS decoding. Thanks in advance for all help.
